【摘要】 由湖南省 1∶10 0万 10′× 15′平均均衡重力异常图知 ,湘西北地区呈重力高 ;除此以外的广大地区 ,当消除花岗岩对应的局部重力低外 ,均衡异常基本呈零值特征。笔者认为这是湖南全省的地壳均衡失调区 ,并从 5个方面对该问题进行了分析更多还原

【Abstract】 It is known from the 1∶1 000 000 10′×15′ average isostatic gravity map that the northwestern Hunan area assumes gravity high, and the other vast areas are basically characterized by zero isostatic anomaly if the local gravity low corresponding to granite is eliminated. The authors consider the northwestern Hunan area to be the isostatic dislocation area in Hunan Province, and make an analysis of this problem from five aspects.更多还原
